To all 'wlw/m 'it 'may crmcifnn:

Be it known theft l, (limones gli. citizen of the lh"l` i. i residing; et Newton, in the con y State oi hlnssnchusctrs, halve invented 3crtnin .new and useful lniprovcnients iii (,"fnrd-` ing-Machine Cylinder end il for; and l do dechire tinA ioiifnsfii full,4clear, sind exact ilr wiptl i vention, such will onshl oth the nrt to which it :ippcrziins use the sinne.

My invention rr to lmprovenicnts in cerding;` machines, und more p51 'cnlarly to the leoder-in cylinders thereof :ind the cord clothing Yfor such cylinders.

The object of the invention is to provide a. cylinder ol' iis character wi o. cord clothing which w i 'take 'the stock an evenly' :nid without hunohes', and which will he ,unich Etc -rnore durable than the clothing non' cornA nionly used.

lith the shove and other ol the invention consists of cert tures of construction, combination ond er rangement oi parts, es will 'he hereinafter described and clniined.

In the accompanying drawings: Fignre 1 is o, side elevation oil the leederdn cylin der of cerding machine having my improved card clothing thereon; Fig. o transverse sectional View through the cylind is a plan view of the enter fece ol, the 1in-` proved card clothing; t is n longitudinal sectional view through the sinne; lligr. 5 is a transverse sectional view through the seine; Fig. is a plan view of the bottom or under 'face ol' the saine Fir. 7 is i transverse sectional View similar to Fig. 5, showing the blank portion or space partially V.filled inwith e strip of leather or the like to ednpt the clothing for handling,r cotton and other fine material; and Fig. 8 is e plan View of e slightly modified form of my improved card clothing'.

Referring to the drawings by numeral, 1

`denotes the lender-in ortnker-in cylinder of' a carding machine or the like, which cylinder is mounted uponv a shalt 2 and may be solid or hollow and of wood, motel or any other materiel.

My improved cord clothingr l is formed in the usuolmanner from n strip or strips 4 of leather or other suitable material, in which ere-provided rows of teeth 5 formed by the projecting end of U-sheped 'pins or staples 6 Fig. 3

r l l spirnllj; upon they c: 1 ner und secured fece of the cylinder.

which ere, as shown.- oi the usual form and construction, but which may he of any other suitnhlo or preferred form.

lili' invention consists in leaving one o1' 60 inorl- Voi-tions or spaces 6 of the outer foce ol thc strip l lilium or without the rows of "wth, so that when the clothing is Wound l"nder ,in the usuel Inanthcroto, the teeth 5 will not 65 @over the entire surliioe of the cylinder. I

prol'orfihlyf wrange these hlimk spaces or porlions o longitudhnilly at one or the other ol the edges ol' the strip, ns shown at 7 in Fig. 8 ol' the drawings, or :it the center 0r other in- 70 tnrncdintc portions' l. the strip of leather, ns shoe-'n ot il, in ifi, so os to provide groups or' rows ol the teeth; hut the blankspeces may also ne in the lorni of smell rectsnular: or

ci; ier shaped portions 9 arranged3 trans- 75 verscly or otherwise, as shown in Fig. 3 of the drawings. i When these blank s aces exs t nd longitudinally ol the strip it wi l he seen that they will ,forni :i spiral space or channel nronnd the cylinder `when the clothing is a-pplied thereto nod the teeth will also 4he zirrimged in spiral rows or groups, es Will-he noted upon rc terence to Fig. l of the drawings. This construction will conse the wool, cotton or other materiel to be fed more evenly from the hopper or the like into the machine, und will prevent the bunching ol the materiel. 'The spiral rows of vteeth will drow the me teriel in strings or strands end the blank s aces or portions coming successively across t ie materiel being fed hy the cylinder, will conse the letter to release or partially4 release tgie materiel to prevent large bunches of the seine heimy 'polled into the machine asis now'v the cese .where the teeth @over the entire surse The revision of the hlefnlz spaces in the card c othing also increases the life of the same, since the machine will not become readily choked v/ith large bunches and hence the teeth will not be L00 mashed down or henti '/ln Fig.V 7 of the drawings, l have the lon itndinally extendin'.r hlenk space partially' led with e strip 10 ol'bleather or other suitable materiel which is wound around the cylinder in seid s ace midloe removably securcdtherein; Thisfil ing stripl 10 is provided to adept the cylinder for hen-`vd` dling cotton or other li ht materiel, and it moy he readily remover when the cylinder is to oe used-for handling Wool, shoddya-nd il@ other heavy materiel.' y' Y From the foregoing description, taken in o1ain1s p Hari thus desoribed my invention, what l nini connection with the accompanying drawings, the construction and operation of the invention .will be readily understood Without requiring a more extended explanation.

'Various changes in the torni, proportion the minor details of Construction may be l* 'ed t( withoiit departing from the prin- N i. p e or sacrificing any of the advantages of this invention, as deined by the appended liew and desire to secure by Lettersp rientY isz- I I eax-ding' machine Cylinder presenting on l L 1 'periphery spiral toothed lines and alteri mately disposed spare linesY each toothed line 1 sfrageee being composed of a plurality of rows of teeth spaced apart 4and disposed in staggered relation, the yspace lines being eaoh of greater width than the spaces between the contiguous teeth in the toothedlines, and a detachable illingstrip arranged in the space lines and having its outer surface disposed in a plane below that of the outer endsof the teeth.

In testimony my hand in presence nesses.
